Bonded Matter is a modern fine jewellery brand working exclusively with lab grown diamonds and coloured gemstones. The brand is built on a clear conviction: that lab grown diamonds belong at the centre of a genuine luxury jewellery brand.

Founded by Linda Ko and Daniel Lohrmann, Bonded Matter brings together deep manufacturing expertise and a digitally native customer experience. Linda's knowledge comes from over a decade alongside her husband's jewellery manufacturing and wholesale operation. She owns the product: design direction, production standards, and quality control at every stage. Daniel founded ikaros, a consultancy building growth engines for scale-ups. He owns the experience: brand, marketing, distribution, and the technology behind the online store.

The brand holds every diamond to standards in the top fraction of all stones globally. Its recommended tier, Signature Quality, requires D or E colour, FL/IF/VVS1 clarity, and Ideal or Excellent cut. Fewer than 1 in 2,300 natural diamonds meet this standard. In lab grown terms, roughly 1 in 16 stones qualify, placing them in the top 6% of all lab grown production. All stones are set in 18K gold or 950PT platinum exclusively.

Bonded Matter launches with five product lines: Bonded (engagement rings), Signature (everyday diamond classics), Solstice (statement diamond pieces), Aura (fancy coloured lab grown diamonds), and Jardin (lab grown emeralds, rubies, and sapphires).

The customer experience is central. The brand combines the trust and personal guidance of the best traditional jewellers with the transparency and accessibility of digital. A concierge service supports customers from first question to final delivery. Every piece carries a lifetime warranty.

Bonded Matter has been working towards B-Corp certification from inception. Every purchase offsets 1 tonne of CO₂ through certified native Australian reforestation with Greenfleet.
